Description

Technical Field

[0001] The utility model relates to the field of leek harvesting equipment, in particular to a multi-row leek harvester. Background Art

[0002] Leek is a common green vegetable with rich nutritional and medicinal value. In recent years, with people's increasing attention to healthy eating and the growth in consumption of leek products, the leek planting industry is gradually growing and developing, and planting technology is becoming more and more large-scale, efficient and ecological. This requires the development of medium and large leek harvesters that meet planting technology to improve leek harvesting efficiency.

[0003] Traditional leek harvesters are mostly small leek harvesters that can only harvest leeks in a single row. They are somewhat weak in the face of large-scale planting, and the harvesting efficiency is low. Moreover, the cut leeks cannot be gathered into piles, but are scattered in the fields, requiring secondary collection, which increases labor. In this regard, CN112042378B discloses a multi-row leek harvester, which simultaneously harvests multiple rows of leeks by arranging multiple groups of straw harvesters and clamping devices on the harvesting table to improve the harvesting efficiency. However, the multiple groups of harvesting heads of the multi-row leek harvester are fixed. When the spacing between the leek planting rows does not match the spacing between the harvesting heads, the planting position deviates or the long distortion is generated, the harvesting operation will be missed or unable to harvest.

[0004] In order to improve the practicality of multiple harvesting heads, CN210470320U discloses a leek harvester, which realizes position adjustment of the cutting head by sliding the cutting head in a slide slot, and makes it easy to harvest leeks at different ridge spacings, thereby improving the practicality of the device. However, the rear-transmission transmission mechanism adopted by the harvester has a long conveyor belt to ensure the feasibility of transportation, resulting in a long fuselage, which is inconvenient to operate during field operations and turning to change ridges, and the direction of the cut leeks on the conveyor belt is consistent with the conveying direction of the conveyor belt. When the slender leeks are transported to the end and fall into the storage bin, only one end falls into the storage bin first. Due to individual differences in leeks or other factors, the directions in which the leeks fall may be inconsistent, making the leeks in the storage bin chaotic, thereby increasing the subsequent picking work.

[0005] Therefore, in order to solve the above-mentioned existing problems, the present application proposes a multi-row leek harvester. Utility Model Content

[0034] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0035] like Figures 1 to 6 As shown, a multi-row leek harvester includes a frame 1, a cutting device 2, a first conveying device 3, a second conveying device 4, a power device 5, a cover plate 7, a distribution device 8, walking wheels 9, and a push handle 10.

[0036] The frame 1 is a frame structure, and the four corners of the frame 1 are equipped with running wheels 9, which are general steering wheels to facilitate the walking of the harvester.

[0037] A cutting device 2 is installed at one side of the bottom of the frame 1. Figure 7 As shown, the cutting device 2 includes a cutting blade 21 and a driver 22 connected to the cutting blade 21. The cutting blade 21 is a long strip blade, and the length of the cutting blade 21 corresponds to the length of the horizontal section of the conveyor belt 33 of the first transmission device 3. In this way, the cutting range is larger, and multiple rows of leeks can be harvested at the same time. Moreover, the cutting range is a surface rather than a point, which solves the problem of missed harvesting caused by differences in planting spacing or distorted growth in traditional multi-head harvesters.

[0038] A pair of push handles 10 are provided on the top crossbar of the frame 1 on the side opposite to the cutting device 2, so as to facilitate pushing the harvester to move.

[0039] A distribution device 8 is installed in the middle of the frame 1. Fig.10As shown, the distribution device 8 includes a distribution frame 81, which is installed on the frame 1 through a rotating shaft 82 and a bearing seat 83. A transmission device 84 is installed at one end of the rotating shaft 82 away from the cover plate 7. When the crossbar of the distribution frame 81 rotates to the cutting device 2, it exceeds the position of the cutting device 2. During operation, the transmission device 84 drives the rotating shaft 82 to rotate, thereby driving the distribution frame 81 to rotate. When the distribution frame 81 rotates to the front end of the cutting device 2, the cut leeks are orderly distributed to the conveyor belt.

[0040] A first conveying device 3 is installed on the frame 1 above the cutting device 2. The other end of the first conveying device 3 extends along the vertical side of the frame 1 to the top of the frame 1. A second conveying device 4 is installed on the inner side of the first conveying device 3. A conveying gap channel 5 is formed between the first conveying device 3 and the second conveying device 4 for conveying the cut leeks to the collecting device.

[0041] The first conveying device 3 and the second conveying device 4 are both connected to the driving force of the power device 6, which drives the first conveying device 3 and the second conveying device 4 to move. The power device 6 is installed above the frame 1 and close to the second conveying device 4; the first conveying device 3 and the second conveying device 4 are surrounded by cover plates 7 for fixing the first conveying device 3 and the second conveying device 4 and also for isolation and protection.

[0042] The first conveying device 3 includes an active roller 1 31, an active roller 2 32, and a plurality of corner transition rollers (specifically arranged at positions as shown in FIG. Figure 5 Figure 6 As shown) and a transmission belt 1 33 connected between the active roller 1 31, the active roller 2 32 and a plurality of corner transition rollers, the active roller 1 31, the active roller 2 32 and a plurality of corner transition rollers are all connected to the cover plates 7 on both sides through a rotating shaft; the transmission belt 1 33 includes a horizontal section arranged at the bottom of the frame 1, a vertical section arranged in the longitudinal direction of the frame 1, and a tail section arranged above the frame 1;

[0043] The second conveying device 4 includes an active roller 3 41, a plurality of corner transition rollers (specifically arranged at positions as shown in FIG. Figure 5 Figure 6 As shown) and a transmission belt 2 42 connected between the active roller 3 41 and a plurality of corner transition rollers, the active roller 3 41 and the plurality of corner transition rollers are connected to the cover plates 7 on both sides through a rotating shaft; the transmission belt 2 42 includes a vertical section arranged in the longitudinal direction of the frame 1 and a tail section arranged above the frame 1;

[0044] The power device 6 includes a motor 61, the output shaft of the motor 61 passes through the bearing seat and is sleeved with a sprocket 62 and a pulley 63, the sprocket 62 is connected to one end of the active roller 1 31 and the active roller 2 32 of the first conveying device 3 through a transmission chain 64, and the pulley 63 is connected to one end of the active roller 3 41 of the second conveying device 4 through a transmission belt 65, and the transmission belt 65 is staggered so that the pulley 63 and the active roller 3 41 rotate in opposite directions. The motor 61 is started to rotate counterclockwise, and the motor 61 drives the sprocket 62 and the pulley 63 to rotate counterclockwise at the same time. The rotational force of the sprocket 62 is transmitted to the active roller 1 31 and the active roller 2 32 through the transmission chain 64, driving the active roller 1 31 and the active roller 2 32 to rotate counterclockwise at the same time, thereby driving the transmission belt 1 33 to move counterclockwise; the rotational force of the pulley 63 is transmitted to the active roller 3 41 through the transmission belt 65. Since the transmission belt 65 is staggered, it drives the active roller 3 41 to rotate clockwise, thereby driving the transmission belt 2 42 to move clockwise. In this way, the inner belts of the two vertical sections close to the transmission belt 1 33 and the transmission belt 2 42 move upward at the same time, and the transmission gap channel 5 formed between the two can transmit the leeks transported from the horizontal section of the transmission belt 1 33 to the top tail section by relying on the clamping support of the belts on both sides, and finally transport them from the tail section of the transmission belt 2 42 to the collection device. The collection device can be placed on the top frame of the frame 1 and connected with the tail section of the transmission belt 2 42.

[0045] The conveying device of the harvester arranges two conveyor belts in a horizontal and vertical combination to form a longitudinal conveying gap channel between the two conveyor belts, which effectively reduces the length of the fuselage while realizing the transmission and collection of harvested leeks. The compact fuselage is more convenient for field operations and turning and changing ridges. Moreover, the conveying directions of the horizontal section and the tail section of the conveyor belt are horizontal, which can ensure that the leeks fall into the collection device in whole beads as much as possible, thereby improving the neatness of leek collection and reducing the subsequent picking and sorting workload.

[0046] Working principle: before harvesting leeks, a collecting device is placed on the top frame of the frame 1 to connect it with the tail section of the conveyor belt 2 42. When working, start the driver 22, the motor 61, and the transmission 84 to make the cutting device 2, the first conveyor device 3, the second conveyor device 4, and the distribution device 8 enter the working state, hold the push handle 10 and push the harvester forward, while the cutting blade 21 completes the cutting action, the distribution frame 81 will orderly distribute the cut leeks to the horizontal section of the conveyor belt 1 33, and the conveyor belt 1 33 will transfer the leeks from left to right to the transmission gap channel 5, and the transmission gap channel 5 relies on the clamping support of the belts on both sides to transfer the leeks upward to the top tail section, and finally transport them from the tail section of the conveyor belt 2 42 to the collecting device to complete the leek harvesting.

[0047] Further preferably, the cutting blade 21 of the cutting device 2 includes a movable blade 211 and a fixed blade 212, the movable blade 211 is placed below the fixed blade 212, and the driver 22 drives the movable blade 211 to make reciprocating linear motion and then engages with the fixed blade 212 to complete the cutting action.

[0048] Further preferably, a moving groove 71 is provided at the connection position between the active roller 31 and the two side cover plates 7, and a tension spring 75 is connected between the rotating shafts at both ends of the active roller 31 and the protrusions 73 on one side of the moving groove 71; a moving groove 2 72 is provided at the connection position between the corner transition roller near the active roller 3 41 and the two side cover plates 7, and a tension spring 2 76 is connected between the rotating shafts at both ends of the corner transition roller and the protrusions 74 on one side of the moving groove 2 72. The active roller 31 and the corner transition roller can move in the moving groove 1 71 and the moving groove 2 72 respectively, and at the same time, with the tension springs 1 75 and 2 76 of different sizes, the tightness of the corresponding transmission belt can be adjusted, so that the transmission gap channel 5 has a suitable clamping force.

[0049] Further priority, such as Fig.10 As shown, a plurality of dividing teeth 85 are evenly distributed on the crossbar of the dividing frame 81 to improve the dividing effect. Example

[0050] The present embodiment is different from the first embodiment in that the harvester can perform harvesting operations on both the front and rear sides. In the present embodiment, a cutting device 2 is also installed on the other side of the bottom of the frame 1, which can be installed by welding or bolting, and a pair of push handles 10 are also provided on the top crossbar of the frame 1 on the opposite side of the cutting device 2. In this way, the harvesting operation can be performed by pushing either side forward, and when changing ridges for harvesting, it is only necessary to push the harvester to the position of the next ridge in a translational manner, and the harvesting can be performed by pushing the other side. In addition, since there is a cover plate 7 on one side of the harvester, if only one side can perform the harvesting operation, after the ridge is changed and turned, there may be leeks in front of the cover plate 7, resulting in obstruction of the forward movement, and this problem can be solved by harvesting operations on both sides.

[0051] It should also be noted that when performing the side-changing harvesting operation, the rotation direction of the distribution frame 81 needs to be switched at the same time. Example

[0052] This embodiment is different from Embodiment 2 in that Figure 8 Fig. 9As shown, in this embodiment, a slide groove 11 is set on the right side of the bottom of the frame 1, and the cutting device 2 is installed in the slide groove 11. The cutting blade 21 can be installed in the slide groove 11 by using a connecting piece such as a tiger clamp or a bolt. When the cutting machine needs to harvest on the other side, it is only necessary to remove the connecting piece between the cutting blade 21 and the slide groove 11, and the cutting device 2 can be slid along the slide groove 11 to the other side of the bottom of the frame 1, and the cutting blade 21 can be installed in the slide groove 11 again by using the connecting piece. Compared with the solution of Example 2, this solution has a low manufacturing cost, but adds a switching step.

[0053] The present invention is described in detail above through specific and preferred embodiments, but those skilled in the art should understand that the present invention is not limited to the embodiments described above, and any modifications, equivalent substitutions, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
